A |     Gandhinagar, Oct 19 (UNI) Prime Minister Narendra Modi is all set to unveil the Hindustan Turbo Trainer-40, the indigenous Basic Trainer Aircraft designed by Hindustan Aeronautics Limited here on Wednesday.

The Prime Minister will inaugurate India's biggest ever five day long defence exhibition DefExpo 2022 at Mahatma Mandir Convention and Exhibition Centre at around 9:45 AM and thereafter visit the India Pavilion to unveil the trainer aircraft.

The HTT-40 aircraft has state of art contemporary systems and has been designed with pilot friendly features.

The aircraft has already received its clearance certificate from Centre for Military Airworthiness and Certification (CEMILAC) based on extensive design evaluation, testing of aircraft systems and comprehensive flight testing carried out by HAL Flight Operations team along with pilots from IAF.

The project also set a record as the fastest to reach certification from the first flight.

In February last year, Hindustan Aeronautics Limited received a Request for Proposal (RFP) from the Indian Air Force for their Basic Trainers requirement at the Aero India 2021 in Bengaluru. The RFP was for 70 HTT-40 Basic Trainer Aircraft with provision for 38 more.

The trainer has more than 60 percent indigenous content and is supported by agencies such as Centre for Military Airworthiness and Certification (CEMILAC), Regional Director Aeronautical Quality Assurance (RDAQA), Aircraft and Systems Testing Establishment (ASTE) among others.

During the programme at the DefExpo 2022, the Prime Minister will also launch Mission DefSpace here to develop innovative solutions for the Defence Forces in the Space domain through industry and startups.

Besides, the Prime Minister will lay the foundation stone of Deesa airfield in Banaskantha district of Gujarat. As per sources, the air base, situated just 130 km from Pakistan border, will be operational by 2024.

The forward airforce base will add on to the security architecture of the country. Experts believe that the strategically located airbase will add teeth to the IAF's prowess along the western border.

Modi is on a two day visit to Gujarat on Wednesday and Thursday where he is set to dedicate and lay the foundation stone of projects worth around Rs 15,670 crore.

UNI ASU BAV。     8 月 26 日消息，科技媒体 NeoWin 昨日（8 月 25 日）发布博文，报道称安全研究员 Xusheng Li 通过逆向分析，发现微软画图（Paint）和微软照片（Photos）会把 GDID 标识符嵌入到 AI 生成的图片中。

B | 注：GDID 最早于今年 7 月报道，在针对 19 岁黑客的 39 页联邦起诉书，指出微软承认在 Windows 11 系统中，内置全局设备标识符（Global Device Identifier，简称 GDID），且没有完整关闭选项。全局设备标识符是微软用于识别某次 Windows 安装实例的持久设备级标识，可关联实体设备或虚拟机，并在部分微软服务中作为统一识别键使用。

C | 典型场景包括设备目录登记、跨设备服务协同、更新分发与企业级状态上报。GDID 以 128 位数值（128-bit value）占用 16 字节（bytes），在微软画图和照片的相关功能中，微软服务器似乎会为提示词分配这类标识符。即使 Copilot 在本地生成图片，用户输入的提示词仍可能先发送至微软服务器。Li 分析微软画图应用的 AI 功能时，发现了 Watermarker.dll 组件。画图本身已经提供可见水印选项，可以在生成图片上添加小型 Copilot 标志；但研究员发现，另一套隐藏水印功能独立于该选项运行。

D | 研究还称，微软会把 C2PA 内容认证（C2PA Content Credentials）添加到 AI 生成图片中。李旭升发现，同一个 watermarkId 也会出现在 C2PA 元数据中，作为一种“软绑定”值，用于关联图片像素中的隐藏水印与图片来源元数据。微软照片也包含 Watermarker.dll。研究员发现，照片中的本地 Image Creator 和 Restyle Image 功能似乎同样会向生成图片嵌入 GDID。
